چکیده

The title compound, C21H14N2O2, was prepared by Pictet-Spengler cyclization of tryptamine and 4-formyl coumarin. In the mol-ecule, the dihedral angle between the mean planes of the coumarin and β-carboline ring systems is 63.8 (2)°. In the crystal, mol-ecules are linked via N-H⋯N hydrogen bonds, forming chains along the b-axis direction. Within the chains, there are a number of offset π-π inter-actions present [shortest inter-centroid distance = 3.457 (2) Å].

Further exploration of the heterocyclic diversity accessible from the allylation chemistry of indigo

Diversity-directed synthesis based on the cascade allylation chemistry of indigo, with its embedded 2,2'-diindolic core, has resulted in rapid access to new examples of the hydroxy-8a,13-dihydroazepino[1,2-a:3,4-b']diindol-14(8H)-one skeleton in up to 51% yield. Additionally a derivative of the novel bridged heterocycle 7,8-dihydro-6H-6,8a-epoxyazepino[1,2-a:3,4-b']diindol-14(13H)-one was produ...

The crystal structures of two title Schiff base derivatives, C15H12N4O·C2H6O (1·EtOH) and C13H13N3O2S (2), were determined at 110 and 100 K, respectively. In the crystal of compound 1·EtOH, the (E)-N'-[(1H-indol-3-yl)methyl-idene]isonicotinohydrazide and ethanol mol-ecules are linked by O-H⋯O, N-H⋯O and N-H⋯N hydrogen bonds, forming a tape structure running along the b-axis direction. The tapes...
